When services are merged, what happens to the monitoring data of individual grouped services?

When services are merged in a monitoring context, the individual monitoring data for the grouped services is aggregated. This means that the detailed metrics and performance data of each individual service are no longer distinguished on a per-service basis but are instead combined into a single set of metrics that represent the overall performance of the merged services. This aggregation allows teams to analyze performance trends and issues at a higher level without the granularity of each service.

Retaining data in full detail would imply that each service's analytics continue to be available separately, which is not the case in a merged service scenario. Similarly, the idea of deleting the data permanently or archiving it for future reference doesn't align with the typical behavior of service merging in monitoring tools, as the data is utilized in its aggregated form for ongoing analysis rather than being discarded or set aside. The primary goal of merging services is to streamline monitoring and simplify management rather than loss of data. Thus, it is essential to understand that the monitoring data becomes available in an aggregate form, enabling a holistic view of the system's health and performance.
